Welcome, tiny comrade.
Various local teams hold regular or semi regular events around the area. All of the fields are semi-official at best, we mostly play where we can.
We organize over Facebook, through multiple groups.
This link is to a general group:

TAAT and PACDT (or RAD lost track of what this team's name is) hold games on occasion, and ORB has games most weekends.
Now I will tell you this, know the rules, play by those rules,be friendly, and keep an open mind. Airsofters are an eccentric bunch and Eugene has a small community on top that. Which tends to intensify that effect.
I'm a major chairsofter, sorry about that.
